Hecate is an open source UART implant framework designed to make common hardware hacking tasks easy with minimal code. It turns any CircuitPython microcontroller into a powerful, customizable UART implant.

In this workshop, you'll get to use all the core features of Hecate and see how they work against multiple target devices. We'll start hands-on by listening to a device's UART output, and then configuring Hecate to operate in standalone mode and log it to a file. Once we've seen it in action, we'll step back for a bit of lecture about UART, what it's used for, and what we designed Hecate to be capable of.
Armed with this knowledge, you'll dive into more hands-on labs: a payload dropper that will playback a custom transaction and a simple detector that will signal an alert when it detects a pattern. We'll reconvene for a last bit of lecture on Hecate's advanced features like in-flight implant-in-the-middle attacks in case you want to explore them after the workshop.

Hecate makes developing embedded implants trivial, while remaining flexible enough for advanced research and rapid prototyping. You'll walk away with hands-on experience using the Hecate framework and a working understanding of what's possible with UART interception, manipulation, and exploitation.
